It is formed of a recycled resin containing a plasticizer for the purpose.
The cable 40 is, for example, covered with a conductor 41 as shown in FIG. 13 with an insulator 42, and some of them are wrapped with a sheath 44 with non-flammable inclusions 43 interposed therebetween. The insulator 42 is made of vinyl (vinyl chloride), and the sheath 44 is also made of vinyl (vinyl chloride). The SV cable recycled product is obtained by regenerating the vinyl (vinyl chloride) resin of the insulator 42 and the sheath 44.

In the CV cable, the insulator 42 is formed of cross-linked polyethylene, and the sheath 44 is formed of vinyl (vinyl chloride). The CV cable recycled product is formed of the cross-linked polyethylene of the insulator 42 and the sheath 44. Recycled vinyl (vinyl chloride) resin.
As said plasticizer, the well-known thing according to the above-mentioned reproduction | regeneration goods can be used suitably.

  The recycled resin forming the cushion body 10 includes 30 to 60 parts by weight of the SV cable recycled product, 20 to 50 parts by weight of the CV cable recycled product, and 10 to 30 parts by weight of the plasticizer. The content of the SV cable recycled product, the CV cable recycled product, and the plasticizer is reduced in the order of the SV cable recycled product, the CV cable recycled product, and the plasticizer.

  The above-mentioned SV cable recycled product is relatively elastic, and the CV cable recycled product has elasticity, but is more rigid than the SV cable recycled product. By containing in the above-mentioned ratio, there is moderate rigidity even while having elasticity, and when the pallet on which the article is placed is placed, the pallet is appropriately bent and supported so as to hold the pallet securely. In addition, the article can be safely held by absorbing vibration such as an earthquake.

In the case where the pallet is made of resin, it is more slippery than wood, but even in such a case, the slip can be stopped by the cushion body 10 installed in the storage rack 1 to securely hold the article. it can.
When load collapse is likely to occur, such as when a large number of articles 5 are placed on the pallet 6, it is often preferable to wrap the articles with a shrink film or the like.

  The recycled resin preferably contains 40 to 50 parts by weight of an SV cable recycled product, 30 to 40 parts by weight of a CV cable recycled product, and 15 to 25 parts by weight of a plasticizer. 45 parts by weight, 35 parts by weight of recycled CV cable, and 20 parts by weight of plasticizer. When the SV cable recycled product is less than 30 parts by weight, the flexibility is low, and when the CV cable recycled product exceeds 50 parts by weight, the rigidity is too strong.
